Proxxon MF70 CNC Conversion Fix for Bubblegum
thingiverse
The part is marked as WIP since I need to fix the face plate on the back. You can already use the parts if you install the original Proxxon plate on the back of the lower axis. The original files for the lower axis are off center on my MF70. I made a new lower motor assembly which works with the original Proxxon screws. v2 Changes * Added Nema 17 mount and ensured it is concentric with the ball bearing pocket + Thicker 4.5x5mm adapter The shaft collar and the M5xM4.5 adapter need M3x10 screws and M3 nuts. Use these until you have your mill setup. Then mill your own ;) The preview image looks a bit rough because it is printed with a 0.6mm nozzle with 0.3mm layers. For final print I'd recommended a layer height of 0.15mm to 0.2mm with a 0.4mm nozzle.
